nspawn,vmspawn: let's add some terminal magic to the welcome text

Let's grey the text out, and prefix it with a vertical grey bar, to make
clear this is output from the host, not the payload, and make it clearly
distinguishable from what follows.

Let's also make the image name clickable (with new enough
shared-mime-info this should allow you to look into the image with
gnome-disk-utility or a similar tool.
